Analýza spolehlivosti železničních kolejových vozidel

Abstract

This diploma thesis deals with the evaluation of reliability of railway vehicles of the class 362/363. The default information’s are data from the guarantee reports and from the SAP system. Then, the parameters of division of distribution functions are estimated via linear regression for groups of elements divided according to the areas given in the system of preventative maintenance. The estimated parameters are then tested by Kolmogorov - Smirnov test of goodness of fit. Then, the parameters of LCC during ten years of operation are estimated considering the costs of corrective and preventive maintenance. Based on the above-mentioned analyses, the measure to increase the reliability and to lower the costs of the corrective maintenance is suggested.
